APPARATUS'FOR REMOVING- OBJECTS FROM A LIQUID BODY.

Application filed May 6, 1918, Serial No. 232,866.

T 0 all whom it mag concern Be it known that I, FRANCIS .CUTTLE, a citizen of the United States, residing at Riverside, in the c unty of Riverside and State of CflllfOI'Ill8.,i3.VB invented a new and useful Apparatus for Removing Objects from a Liquid Body, of which the following is a specification.

,In general the invention relates to an apparatus for lifting objects out of a liquid body and it is illustrated in the drawings as it would be embodied to prevent the passage of fish from one portion of a stream to another or from a natural stream to an irrigation channel, and also for removing debris porated in a fruit washer.

An important object of the invention is the closing of the stream to the passage of fish and debris and also the removal of the latter.

An object of the invention is to provide a device of this character 'of comparatively simple construction and one which is efficient in operation and not liable to get out of order.

Another object is to provide in a machine of this class for great durability and comparatively little wear so that it may be operated continuously for long periods of time with little or no attention being given it.

Other objects and advantages will-appear in the subjoined detail description.

The accompanying drawings illustrate the innention:

cially formed as indicated in the drawings in which the bottom of the container is indicated at 1 and the sides at 2, 3. A rotary or revolving drum 4 is provided in the container. The drum may be made of any suitable material and, if intended to permit liquid to flow therethrough, as when it functions as a screen to prevent the passage of fish up-strea fn, the drum may be in the form of a screen, and, in the instance shown in the drawings, the drum is constructed as follows: A series of spaced bars in the form of rings a forming a permeable drum are seated in notches 6 of cross bars 7 which are fastened at their ends by rivets 8, or equivalents, to arms 9 projecting from a hub lO which is journaled at each end by nonfriction bearings 11 on brackets 12. The brackets 12 are provided with upwardly diverging arms 13 and the arms of each bracket are connected with one another by a flange 14 which may be fastened by lag bolts 15, or equivalents, to the upper edge of the container sides 3. Thus the brackets 12 are held stationary while the hubs 10 are free to rotate on the brackets.

The hub 10 is provided with an internal spur gear 16 meshing with a spur pinion 17 mounted on a shaft 18 which extends transversely of the container and which is journaled in bearings 19 that may be mounted on or constitute portions of the bracket flanges 14. This. shaft 18 is driven by suitable means and, in the instance shown in the drawings, is provided at its opposite ends with bevel gear wheels 20 meshing with other bevel gear wheels 21 on-shafts 22 which extend at right angles to the shaft 18 and longitudinally with respect to the container. The

shafts 22 are journaled in bearings 23, 24 on the sides 2 and 3 and are provided with bevel gears 25 meshing-with other bevel gears 26 on a countershaft 27 which extends transindicated .in general by the character 33,

said shaft being journaled in bearings 34 -mounted on the upper edges of the container sides 2 and 3. This paddle wheel 33 is driven by the water flowing throughthe container and it is clear from the foregoing description of the driving connections that if the stream of water be flowing to the left in Fig. 2 the paddle wheel will be caused to rotate clockwise as indicated by the arrow a and that such rotation will cause counterclockwise rotation of the rotary screen as indicated by the arrow b.

The invention in its broader aspects is not limited to the use of the particular driving connections described above since the screen may be driven by other means, if desired.

, Movably mounted on the revolving drum so as to be rotated by rotation thereof are rake teeth 35. The inner end portions of the teeth 35 are seated in notches 36 of supporting bars 37 which, in the instance 4 shown, are in the form of channels, the

notches being in both flanges thereof. The teeth 35 are clamped to the bars 37 by rods 38 which pass through perforations 39 in the teeth, there being hook-shaped bolts 40 hooked over the rods 38 and extending through the channels 37 to bolt the rods 38 to the channels. These bolts 40 also fasten the channels 37 to reciprocative members in the form of bars 41, said bars being positioned near the opposite ends of the channels 37. The teeth 35 and reciprocating bars 41 are of such lengths that when the outer ends of the teeth 35 at one side of the drum are flush with the peripheries of the screen bars 5 the outer ends of the teeth at the opposite side of the drum will protrude in raking position beyond the periphery of the drum as clearly shown in Fig. 5. The teeth 35 need not necessarily be interposed between each two adjacent screen bars 5, as is readily understood, but such construction is preferred and is shown in Fig. 6 of the drawings. Suitable guides are provided for the teeth 35 and in the instance shown said guides comprise outer bars which may be two of the bars 7, said guides also comprising inner bars 44 fastened by rivets 45, or equivalents, to the arms 9 and also fastened by rivets 46, or equivalents, to the hub 10.

Means are provided to shift the reciprocative bars 41 endwise so as to alternately move the teeth 35 out and in, the teeth at either side being moved outward while those at the other side are being moved inward. This movement of the teeth is accomplished while the drum is rotating and rotation of the drum, in this instance, causes said movement. Movement of the bars 41 may be produced by various means without limiting the invention in its broader phases and, in the instance shown in the drawings, the construction relied upon to effect the move-' ment'is as follows: The bars 41 are provided on their outer faces with rollers 47 which are journaled on studs 48 projecting 'Frnm flan nnl'nr Far-0e n-F flu) \nwc A1 TL.

during that portion of the rotation of the drum in which the teeth 35 project beyond the periphery of said drum. The cam-ways 49 are of such shape as to effect. this move- -ment of the teeth 35. At the point d which represents the end of the instroke of the teeth 35 there is provided a downwardly and outwardly sloping chute 50, the inner end of said chute being as close as possible to the peripheries of the screen bars 5 so that debris may be practically scraped from the periphery of the drum as it rotates.

The revolving drum is placed as close to v the bottom 1 of the channel as it is possible to do without the teeth 35 striking said bottom but, since the teeth are forced downward somewhat below the level of the lower side of the drum periphery, it is advantageous to place afiller strip 51 transversely of the bottom so as to substantially fill in the space between the periphery of the drum and the bottom of the channel excepting for slight clearance between the strip and the periphery of the drum, thus to prevent fish from passing beneath the revolving drum.

The outer end of the chute 50 discharges into a conveyer 52 extending transversely of the channel. In the instance shown in the drawings the conveyer is in the form of an ordinary scraper conveyer having a material-supporting surface 53 and flights 54 to move over said surface so as to impel material along the surface and discharge it at one end of the conveyer to one side of the container. The flights 54 are connected at their ends to the endless conveyer chains 55 which are each love around sprocket wheels Rotation of the drum will carry the teeth 35 around with it thus moving the rollers 47 in the cam-ways 49. Assuming that the drum parts are in the positions shown in Fig. 5, it is clear that the teeth ,35 at the right side of the drum will be held protruding from the periphery of the drum to said teeth will then be gradually retracted so as to pass beneath the inner edge of the chute 50. During this movement of'these teeth, the retracted teeth at the opposite side of the screen will be moved downward while.

to scrape any debris, that will not readily discharge from the drum, oil of said drum; The debris slides or is pushed from the chute 50 onto the conveyer 52 and the flights 54 of said conveyer discharge the debris therefrom at one end of sand conveyer to one side of the container.

It is understood that the invention is not limited to the specific construction shown in the drawings and hereinabove described but that changes may be made therein within the spirit and scope of the appended claims.
